Procurement Using an External Procurement System 

Use

Using this function you can order materials or services in an external procurement system from maintenance orders, service orders, and networks, for example SAP Enterprise Buyer (EBP).

Integration

You can transfer material components or services for which you want to create a purchase requisition (PReq) from an external catalog using the open catalog interface (OCI) (see Catalog Interface (OCI- Open Catalog Interface)).

Prerequisites

·        You installed the SAP R/3 Plug-in for the EBP.

You require this plug-in even if you do not use the EBP, but rather a different external procurement system.

·        In the Customizing of the Plug-In system, under Supplier Relationship Management → Planning-Controlled Procurement, you determined in which system (external procurement system or SAP system) purchase order handling for a purchase requisition should take place.

You can also use the Customer Exit BBPK0001 and thus determine your own logic in the purchasing profile.
